Excel Add-ins: Automate Data and Workflows with Office.js
5 min read
Excel remains the backbone of business data for many organizations. Custom add-ins can automate repetitive tasks, pull data from APIs, enforce formatting, and integrate with your backend.
This post focuses on the Excel JavaScript API: reading and writing ranges, working with tables and charts, defining custom functions (custom functions), and using the request context batching for performance. We also cover scenarios like refreshing data from a service, validating input, and pushing results to SharePoint or your database.
Whether you need a simple task pane that fills a template or a full dashboard that talks to Microsoft Graph and external APIs, the same patterns apply: get the workbook context, queue operations, and run context.sync(). We'll show real-world examples and tips for avoiding common pitfalls.
